I have never had to restart my unit to download the software. It is a little slow and chunky. I have found if I only load the state of Maine on the GPS that it is a little faster or it seems so. I had the whole east coast on it before from Floridia to Maine.
Well as of today I have not heard from anyone and am still without a GPS. I think this is what is irrating me the most that with the fact that I can not get an answer as to when to expect a return or arrange pickup on the unit. Most of the issues that my 2nd unit had seemed to be worked out till I tried to take it Kayaking. I assume it is just a bad seal but after waiting a week now and not getting any responce from delorme is frustrating. As for the rechargable batteries it is not good for a weekend of heavy caching but that is why I have my other batteries. We will see if I acctually here from someone tommorrow.
I have had my PN-20 since the beginning of March and Have had no problems with it. I think it's great for geocachng. I like it better than the Garmin that I had.
